Briefly: the PUNCH mission to monitor the Sun states that they are still tracking interstellar object 3I/ATLAS, even though the small body has passed “behind” the Sun (as seen from Earth). In other words, ‘solar conjunction’: bsky.app/profile/kwalsh4a.bsky.social/post/3m2rnxlgigs2v “While 3I Atlas… Read More »PUNCH Sun Conjunction Mention
